Jackery and EcoFlow are the two names most people shortlist first for a portable power station. Both sell LiFePO4 models from about 250 Wh to 5 kWh, both advertise 5-year warranties, and both have big solar panel lineups. So which one should you buy?
The honest answer depends on the size you need. Below, we compare the two brands’ current US models head to head in three size classes.
How we compared: we used the specs published on Jackery’s and EcoFlow’s official US websites. We have not tested these units ourselves. Prices change constantly, so check the current price through the links.
The short version
- EcoFlow wins on specs at every size we compared: more AC output, faster wall charging, faster UPS switchover and the option to add batteries, plus much more solar input in the 1 kWh and 2 kWh classes.
- Jackery wins on weight and simplicity in the 1–2 kWh class, and its SolarSaga panels plug straight in.
- Jackery’s cycle ratings use a lower bar (4,000 cycles to 70% capacity vs EcoFlow’s ratings to 80%), so the numbers aren’t directly comparable.
Small: Jackery Explorer 300 v2 vs EcoFlow RIVER 3 Plus
| Jackery Explorer 300 v2 | EcoFlow RIVER 3 Plus | |
|---|---|---|
| Capacity | 288 Wh | 286 Wh |
| Battery | LiFePO4, 4,000 cycles to 70% | LiFePO4, 3,000 cycles to 80% |
| AC output | 300 W (600 W surge) | 600 W (1,200 W X-Boost) |
| Wall charging | ~76 min to full | ~1 hour to full |
| Solar input | Via USB-C (100 W max) | Yes (see listing for limits) |
| UPS | Yes (20 ms per Jackery’s FAQ) | <10 ms |
| Expandable | Not listed | Yes, to 858 Wh |
| Weight | 8.16 lb | 10.4 lb |
| Warranty | 3 + 2 years | 5 years |
Winner: EcoFlow RIVER 3 Plus. Twice the AC output and expandable to 858 Wh. The Jackery is lighter and fine for phones, laptops, lights and a CPAP without humidifier (about 6 hours at 40 W), but its only input besides AC is USB-C, so solar charging needs an adapter.

Mid-size: Jackery Explorer 1000 v2 vs EcoFlow DELTA 3 Plus
This is the class most people buy for camping, CPAP and short outages.
| Jackery Explorer 1000 v2 | EcoFlow DELTA 3 Plus | |
|---|---|---|
| Capacity | 1,070 Wh | 1,024 Wh |
| Battery | LiFePO4, 4,000 cycles to 70% | LFP, 4,000 cycles to 80% |
| AC output | 1,500 W (3,000 W surge) | 1,800 W (3,600 W surge) |
| AC outlets | 3 | 6 |
| Wall charging | 1.58 h; ~50 min in app-enabled emergency mode | 1,500 W input, ~56 min to full |
| Solar input | 2 × DC8020, 400 W max combined | 2 × 500 W (11–60 V) |
| UPS switchover | <20 ms | <10 ms |
| Expandable | Not listed | Yes, up to 5 kWh |
| Weight | ~23.8 lb | 27.6 lb |
| Warranty | 3 + 2 years | 5 years |
Winner: EcoFlow DELTA 3 Plus for home use, Jackery for carrying. The DELTA 3 Plus has more outlets, more than twice the solar input, a faster UPS and room to grow. The Jackery is about 4 lb lighter and has slightly more capacity.
What that means in practice: with about 85% of capacity usable through the inverter, either one runs a 60 W average fridge for roughly 14–15 hours or a 40 W CPAP for about 22 hours. In full sun at 75% of max input, the DELTA 3 Plus could refill from solar in about 1.4 hours with 1,000 W of panels; the Jackery needs about 3.6 hours with its 400 W maximum.

Large: Jackery Explorer 2000 v2 vs EcoFlow DELTA 3 Max Plus
| Jackery Explorer 2000 v2 | EcoFlow DELTA 3 Max Plus | |
|---|---|---|
| Capacity | 2,042 Wh | 2,048 Wh |
| Battery | LiFePO4, 4,000 cycles to 70% | LFP, ~10-year lifespan claimed |
| AC output | 2,200 W (4,400 W surge) | 3,000 W (6,000 W surge) |
| AC outlets | 3 | 4 (20 A) |
| Wall charging | ~1.75 h | 1,800 W input, 0–80% in 64 min |
| Solar input | 400 W max (2 × DC8020) | 1,000 W max |
| UPS switchover | <20 ms | <10 ms |
| Expandable | No | Yes, 2–10 kWh |
| Weight | ~39.5 lb | ~48.7 lb |
| Warranty | 3 + 2 years | 5 years (3 + 2 with app registration) |
Winner: EcoFlow DELTA 3 Max Plus. At 2 kWh, solar input becomes the deciding spec: the Jackery’s 400 W limit means about 6.8 hours of strong sun to refill, versus roughly 2.7 hours for the EcoFlow with 1,000 W of panels. The EcoFlow also runs bigger loads and expands to 10 kWh. The Jackery is about 9 lb lighter.

What about whole-home backup?
Both brands sell 120/240V systems, such as the Jackery Explorer 5000 Plus and the EcoFlow DELTA Pro 3. When we checked, EcoFlow’s site listed the DELTA Pro 3 as currently unavailable, and several new EcoFlow models were on pre-order. For that tier, compare the specs and availability carefully before you buy.
Brand differences that matter
- Solar connectors: Jackery stations use DC8020 inputs, and SolarSaga panels ship with an adapter; EcoFlow sells XT60-type solar cables. Third-party panels work with both if voltage and current are within limits.
- Warranty: Jackery’s 5 years is 3 standard plus 2 extended when you buy from Jackery or an authorized seller; EcoFlow’s newer models are 3 plus 2 with app registration.
- Cycle ratings: Jackery quotes cycles to 70% capacity, EcoFlow to 80%. A Jackery and an EcoFlow both rated at 4,000 cycles aren’t equivalent on paper.
- Model names: Jackery has renamed some models on its site (the Explorer 3000 v2 page now shows “HomePower 3000”), so double-check the exact model in a listing.
What owners say
We read owner discussions across several communities:
- Most owners call it a tie. In a long comparison thread, most posters said the brands are roughly equal and to buy on price and size; EcoFlow owners reported years of trouble-free use, including an expanded unit powering a shop. (SIGforum)
- Customer service is the swing factor. Opinions on support were mixed for both brands, and several owners preferred buying through big retailers for easier returns. (Rivian Forums)
- Jackery’s panels are easier to pair. An owner of both brands said both work as designed but found Jackery’s panels simpler to set up with its stations. (Footballguys Forums)
- Fans run while charging. EcoFlow owners said the fans spin up during charging but stay fairly quiet and run briefly because charging is fast. (MotorhomeFun)
The bottom line
If you want the most capability per dollar, buy EcoFlow: at each size we compared, it has more output, faster charging, more solar input and expansion. Buy Jackery if you’ll carry it often and want a light, simple unit with matching panels, especially the Explorer 1000 v2. Either way, decide on size first: around 300 Wh for day trips, 1 kWh for camping and CPAP, 2 kWh or more for outages.

Frequently asked questions
- Is Jackery or EcoFlow better?
- On published specs, EcoFlow usually offers more AC output, faster wall charging, more solar input and expandable batteries at each size. Jackery is often lighter and simpler, with a well-matched SolarSaga panel range. Owners in forums mostly call them roughly equal in reliability.
- Can I use EcoFlow solar panels with a Jackery, or vice versa?
- Often yes, with the right adapter, as long as the panel's voltage and current stay within the station's input limits. Jackery stations use DC8020 inputs, while EcoFlow stations commonly use XT60-type inputs.
- Which brand has the better warranty?
- Both advertise five years on current models. Jackery's is 3 years standard plus 2 extended when bought from Jackery or an authorized seller; EcoFlow's newer models are 3 years plus 2 with app registration.
- Which is better for home backup?
- For short outages, a 1–2 kWh model from either brand works. EcoFlow's expandable models and faster UPS switchover give it an edge for backup, but check availability, as several large models were sold out or on pre-order in November 2026.
